Abstract

The present invention is to provide a mechanism comprising a sliding assembly having a portion mounted in a fixed assembly and adapted to move a predetermined distance defined by the fixed assembly, wherein the sliding assembly has another portion for connecting with a support and the fixed assembly is connected to a body; and a resilient member being interconnected to with the fixed assembly and the sliding assembly. In response to exerting an elastic winding force or unwinding force by the resilient member the sliding assembly is adapted to slide with respect to the fixed assembly and a balance of force between the fixed assembly and the sliding assembly is reached when the sliding stops for maintaining both the support and the body at an angle about the supporting surface.

Claims

1. A mechanism for enabling one-hand adjusting of a viewing angle of a flat display about a supporting surface comprising:

a body;

a fixed assembly having a rear surface connected to a front surface of the body such that the body is adapted to move as the fixed assembly moves;

a sliding assembly having a portion mounted in the fixed assembly and adapted to move a predetermined distance defined by the fixed assembly;

a support having a top disposed at a bottom of the sliding assembly and a bottom disposed on a supporting surface for supporting the body; and

a resilient member interconnected to the fixed assembly and the sliding assembly, wherein in response to exerting an elastic winding force or unwinding force by the resilient member, the sliding assembly is adapted to slide with respect to the fixed assembly and a balance of force between the fixed assembly and the sliding assembly is reached when the sliding stops for maintaining both the support and the body at an angle about the supporting surfaces,

wherein the sliding assembly comprises;

a receptacle disposed inside the sliding assembly facing an inner surface of the fixed assembly for receiving the resilient member; and

two L-shaped flanges disposed at both sides of the sliding assembly projected toward the fixed assembly, each flange being adapted to form a channel with respect to the side of the sliding assembly;

wherein a plurality of first holes are disposed at a lower portion of at least a first side of the sliding assembly, a plurality of second holes are disposed at an upper portion of at least a first side of the support and are disposed corresponding to the first holes, and a plurality of first fasteners are driven through the first holes and the second holes to fasten the support at the sliding assembly;

wherein the resilient member is shaped as a roll of elastic member and is adapted to return to its original winding state after a force of extending itself is removed, one end of the resilient member is formed as a sleeve and the other end thereof is fastened at the fixed assembly, a hollow cylinder is respectively fitted in each end of the sleeve, and a pin is inserted through the cylinders having both ends respectively anchored in a slot at a side of the receptacle, and

wherein the resilient member is adapted to rotate about the slots of the receptacle when the resilient member winds or unwinds for moving both the fixed assembly and the sliding assembly.

2. The mechanism of claim 1, wherein the fixed assembly comprises:

a frame of U-section formed at its central portion, the frame including a board extended outwardly from both sides thereof, the boards being secured onto an inner surface of the body such that the body is adapted to move toward the fixed assembly as the boards move, and a plurality of third holes disposed on a main portion of the frame proximate the sides of the frame;

two buffer members; and

a plurality of second fasteners driven through the third holes to cause the buffer members to respectively contact the first side and a second side of the sliding assembly wherein the buffer members are fitted into the channels and the channels are adapted to slide about the buffer members.

3. The mechanism of claim 2, wherein each buffer member comprises:

an elongate block; and

an elongate groove member of U-section, wherein the block is fitted in a space defined by the groove member, the groove member is adapted to fasten between the block and the fixed assembly, and the groove member is fitted in the channel.

4. The mechanism of claim 3, wherein the groove member is formed of plastics.

5. The mechanism of claim 3, wherein the groove member is formed of rubber.

6. The mechanism of claim 3, further comprising a stop member disposed at each side of the fixed assembly, the stop members being adapted to prevent the resilient member from extending over its predetermined extent when the channels slide downward along the groove members.

7. The mechanism of claim 1, wherein the body is a flat display.
